WEATHER-STRIP.

To all whom it may concern:

Be it'known that I, CHARLES A. PIKE, a citizen of the United States,residing at the village of Paw Paw, county of Van Buren, State ofMichigan, have invented certain new and useful Improvements inWVeather-Strips, of which the following is a specification.

This invention relates to improvements in weather strips for doors.

The main objects of this invention are: first, to provide an improvedweather strip for .doors by which the wear on the floor or door sill andon the weather strip is reduced to a minimum. Second, to provide animproved weather strip for doors adapted to form a very tight joint whenthe door is closed, and one which does not materially add to the powerrequired to open or close the door. Third, to provide an improvedweather strip for doors embodying the above features, which isautomatically controlled by the opening and closing of the door, itbeing adapted to automatically open on the opening of the door and toautomatically close on the closing of the door. Fourth, to provide animproved weather strip for doors embodying the above advantages which isa simple and economical structure and may be readily applied without inany way mutilating the door to which it is applied.

Further objects, and objects relating to structural details, willdefinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and meansdescribed in the following specification.

The invention is clearly define d and pointed out in the claims.

A structure embodying the features of my invention is clearlyillustrated in the accompanying drawing, forming a part of this specification, in which,

Figure 1 is a detail elevation of a structure embodying the features ofmy invention, the open position of the parts being indicated by dottedlines. It will be understood, however, that they do not assume thisposition while the door is closed. Fig. 2- is an enlarged detail sectiontaken on a line corre sponding to line 22 of Fig. 1. Fig. 3 is a detailsection through the levers 8, taken on I a line corresponding to line 38of Fig. 1, showing the connection for the levers. Fig. 4 is a detailvertical section, taken on a line Specification of Letters Patent.

corresponding to line 4-4 of Fig. 1, showing 1details of the weatherstrip or plate-lifting ever.

In the drawing, the sectional views are taken looking in the directionof the little arrows at the ends of the section lines, and similarnumerals of reference refer to similar parts throughout the severalviews.

Referring to the drawing, 1 represents the wall of a building 2 the doorframe or casing; and 3 the floor or door sill. The door 4 is hung onsuitable hinges, but as these form no part of this invention they arenot here illustrated.

The weather strip or plate 5 is arranged across the bottom of the door,and secured thereto bythe screws 6 which are arranged in the verticalslots 7 in the plate. These screws also serve as supports for the leversS, which are pivotally mounted thereon. The levers 8 are pivotallyconnected at their outer ends as by the screws 9 to the plate. The innerends of the lovers are connected by the rivet 10 carried by one of thelevers, which is adapted to engage a suitable slot, as 11, in the other.By thisconnection the plate is guided so that it is impossible for it towedge or bind in its movement in opening or closing.

The weather strip or plate is preferably provided with a facing 12 offelt, rubber or other suitable material, for its lower edge.

The inner ends of the levers S are held normally upward by means of thespring 13, the free end of which is connected thereto by suitable linkas 14, the other end of the spring being mounted upon the plate by meansof a suitable stud 15.

It is obvious that through the connection of the lovers to the door,when their inner ends are held upward, the weather strip or plate isthrown down to the position indicated by full lines in the drawing.

When the door is open, the plate is ele vated by means of the lever 16which is actuated by a spring 17. The spring 17 is connected to thelower end of the lever and to the stud or post 18 projecting through aslot 19 provided therefor in the plate, the stud being carried by thedoor. The lever 16 is provided with a curved arm 20 which is adapted toengage the pin 21 on the plate, so that the spring serves to hold theplate normally upward. This spring is of sufiicient durable.

. inner ends of said levers to lift the same,

other at their inner ends, and to said plate strength or tension toovercome the tension 1 of the spring 13, so that, unless the lever 16 isheld out of its engaging position, the plate is held normally upward.

The lever 16 is arranged vertically and is mounted on a suitable pivotas 22, arranged through a vertical slot 23 in the plate, as clearlyappears in Fig. 4. WVhen the door is closed, the lever is engaged by thetrip pin 24 which forces its upper end inwardly, thereby releasing theplate 5, allowing the spring 13 to close the same. As soon, however, asthe door is open, the lever is released, so that the spring 17, actingtherein, lifts the plate against the tension of the lever 13, holding itopen. By this simple means, I secure a weather strip for doors, which,while it is very tight when closed, is automatically opened upon theopening of the door so that the wear on the weather strip and upon thedoor sill or floor is minimized, it being in fact practically nothing.The structure is very simple and at the same time strong and I haveillustrated my improved weather strip in detail in the form preferred byme on account of its structural simplicity and economy. I am, however,aware; that it is capable of considerable variation in structuraldetails Without departing from my invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
